摘要:
In a power transmission apparatus for a vehicle having a gear transmission capable of transmitting power from a crankshaft of an engine to driving wheels by selectively establishing a plurality of shift stages of gear trains and a clutch for cutting power transmission from the crankshaft to the gear transmission in operating to shift the power transmission, when the clutch is operated to cut or connect in cooperation with the shift operation of the gear transmission, shift operability is promoted while avoiding an increase in weight. A gear transmission is shifted by a first actuator and a clutch is driven by a second actuator which is independent of the first actuator.

To enable preventing interference between a honing machine and a journal wall, avoiding large-sizing of a cylinder block and tilting a front cylinder part so that the upper end is as low as possible in a vehicular V-type internal combustion engine wherein the front cylinder part arranged on the front side in a vehicular travel direction and a rear cylinder part arranged on the rear side in the vehicular travel direction are arranged so that they form an approximate V-shape. A front cylinder part is tilted so that the upper end is lower than that of a rear cylinder part and a bent part bent on the side distant from a central position is formed in a part corresponding to a front cylinder hole of a journal wall arranged on the side displaced from the central position between both journal walls of the front cylinder hole.

An automatic transmission that includes oil passages with a simple structure provided for twin clutches can allow the number of production steps to be reduced. In an automatic transmission includes a number of gear trains equal to the number of speeds between a primary shaft and a countershaft. The automatic transmission performs connection and disconnection of a rotational driving force between a crankshaft and a gearbox by means of twin hydraulic clutches including first and second clutches. The first and second clutches are disposed on the axis of the primary shaft back to back with a primary gear interposed therebetween. Oil passages can be formed into a more simple shape than those formed by a method in which twin clutches are accommodated in a single case and can be configured to have the same total length. The first and second clutches are made of the same components. The first clutch performs connection and disconnection for first and third speeds, and the second clutch performs connection and disconnection for second and fourth speeds.

A method of manufacturing a ferritic stainless steel sheet having good workability with less anisotropy. The steps include providing a ferritic stainless steel comprising C up to about 0.03 mass %, N up to about 0.03 mass %, Si up to about 2.0 mass %, Mn up to about 2.0 mass %, Ni up to about 0.6 mass %, Cr about 9–35 mass %, Nb about 0.15–0.80 mass % and the balance being Fe except inevitable impurities; precipitation-heating said stainless steel at a temperature in a range of 700–850° C. for a time period not longer than 25 hours; and finish-annealing said stainless steel at a temperature in a range of 900–1100° C. for a time period not longer than 1 minute.
摘要:
A power transmission apparatus for an engine of a vehicle. The apparatus includes a starting clutch for smoothly connecting rotation of a crankshaft to a transmission upon starting of the vehicle, a hydrostatic continuously variable transmission for performing speed change depending upon a capacity difference between a swash plate hydraulic pump and a swash plate hydraulic motor to transmit rotation of the crankshaft at a reduced speed to a driving wheel, and a slider for moving a ball screw back and forth to change the angle of the swash plate of the swash plate hydraulic motor. The starting clutch can be a torque converter.

A transmission of an internal combustion engine is used in a saddle-type vehicle (buggy) for running on rough terrain. A crankshaft of the vehicle is arranged so that it is parallel with the traveling direction of the body. The transmission includes a mechanism for switching a gear for forward travel and a gear for backward travel. At least a part of the mechanism for switching the gear for forward travel and the gear for backward travel is provided between a crankcase and a crankcase cover. At least one of shafts forming the switching mechanism is partially overlapped with a main shaft or a counter shaft in the axial direction.

In a power transmission path of a vehicle for traveling on uneven ground, a torque converter is provided so that torque transmission to a propeller shaft varies smoothly. Accordingly, it is difficult for the torque transmitted to the propeller shaft to exceed a tire slip limit. This arrangement suppresses slippage during traveling on uneven ground such as a muddy, marshy, sandy, snowy, or gravel road surfaces.
摘要:
To provide a four-cycle engine for a vehicle, in which a cylinder bore is disposed in such a manner that the axial line thereof extends substantially in the horizontal direction. Furthermore, a cam shaft is disposed between an intake valve and an exhaust valve which have operational axial lines crossing each other in an approximately V-shape. The engine is capable of making the position of the outer end portion of an exhaust valve as close to the axial line of a cylinder bore as possible, thereby making the mounting position of the engine as low as possible. A cam shaft is disposed above the axial line of a cylinder bore and on a projection plane perpendicular to the axial line of a crank shaft, including the axial line of the cylinder bore. Furthermore, an angle formed between the axial line of the cylinder bore and the operational axial line of an intake valve is set to be larger than an angle formed between the axial line of the cylinder bore and the operational axial line of an exhaust valve.

To provide a breather apparatus for a horizontally-opposed type or a V-type engine in which first and second cylinder blocks having first and second cylinder bores are commonly connected to a crank case in such a manner that the axial line of the first cylinder bore is offset from the axial line of the second cylinder bore to one side of the crank shaft along the axial line of the crank shaft. A cam chain chamber is provided in the crank case, the cylinder blocks and the cylinder heads on one side of the crank shaft along the axial line of the crank shaft. Furthermore, a breather chamber is formed in the second cylinder block, the second cylinder head, and the crank case at a position between the cam chain chamber and the second cylinder bore. The breather chamber has a relatively large capacity, while enlargement of the engine is avoided.

A control system for a dust collecting apparatus including an upright housing arranged above a dust storage bin, a ceramic filter assembly disposed within the housing to collect dust particles from exhaust gases supplied into a bottoms portion of the housing located upstream thereof, and a reverse washing mechanism mounted on the housing downstream of the filter assembly to cause the collected dust particles to fall into the dust storage bin from the filter assembly when it is activated, wherein temperature (T1) and pressure (P1) of the exhaust gases supplied into the housing upstream of the filter assembly, temperature (T2) and pressure (P2) of purified gases discharged from the filter assembly into an upper portion of the housing located downstream of the filter assembly and a flow quantity (Q1) of the purified gases discharged from the housing downstream of the reverse washing mechanism are detected to calculate an average temperature T=f(T1, T2), a flow quantity �(Q=f(Q1. T)!, viscosity (.eta.=f(T) and a pressure loss coefficient K=f(.DELTA.P, Q, .eta.) of the exhaust gases passing through the filter assembly, and wherein the reverse washing mechanism is activated under control of an electronic controller when the calculated pressure loss coefficient (K) becomes more than a predetermined value (K0) and is deactivated when the calculated pressure loss coefficient becomes less than the predetermined value (K0).
