Abstract:
A tubular vibration damping device has a structure in which an inner shaft member is connected with an outer tube member made of synthetic resin by a body rubber elastic body. The outer tube member has a structure in which a tubular part extends in an axial direction from an inner peripheral end of a flange of an annular plate shape. A press fit rubber is fixed to an outer peripheral surface of the tubular part, and an axial surface of the flange on a side from which the tubular part extends is exposed without being covered with the press fit rubber. A notch penetrating in a radial direction is provided at an axial end of the outer tube member that includes the flange. A connecting rubber that connects the body rubber elastic body and the press fit rubber is provided in the notch.

A structure for mounting an engine mount, may include bracket which is coupled to the engine mount, and may have at least one mounting hole; an insulator which may have a pipe shape having a center hole, includes a material having elasticity, and is fitted into the at least one mounting hole; and a fixing pipe which is fitted into the center hole, and mounted in the at least one mounting hole together with the insulator, in which a recessed portion having a partially cut out shape or a recessed shape is formed along a circumference of the insulator at a first side of the insulator.
Abstract:
A first engine mount unit sharing no distributed load of a power unit includes: a power unit side bracket attached to the power unit; a vehicle body side bracket attached to a vehicle body; and a mount rubber provided between the power unit side bracket and the vehicle body side bracket. At attachment portions of the power unit side bracket and the vehicle body side bracket of the first engine mount unit, a bolt hole is provided in an inner cylinder part adhered to the mount rubber pressed into the power unit side bracket, to adjust variations in the height direction (H direction) of the vehicle, while bolt holes are provided in the vehicle body side bracket to adjust variations in the width direction (W direction) of the vehicle.
Abstract:
Disclosed herein is an engine mounting structure for reducing vibration. In particular, an engine having a mass is mounted to a damper pulley or a drive plate thereof to form an outer balancer. A roll mount is positioned on a virtual yaw axis after the virtual yaw axis is set in the engine, and an engine mount is mounted to one end of a virtual torque roll axis after the virtual torque roll axis is set in the engine. Furthermore, a transmission mount is mounted to the other end of the virtual torque roll axis. Therefore, the mounts are mounted to the engine to reduce vibration at the time of idle vibration, thereby making it possible to improve NHV performance of a vehicle and increase salability and driving convenience of a driver.
Abstract:
An assembly bearing structure of a motor vehicle which is favorable in crash situations includes a holding arrangement disposed on the vehicle body. This holding arrangement includes a carrying member supported on the vehicle body as well as an elastically connected longitudinal support which is provided with a catch device for a front-side end of a transmission case and has at least one energy-absorbing deformation area.
Abstract:
A mount bush includes an internal pipe, a middle pipe disposed outside the internal pipe, a main rubber vulcanized between the internal pipe and the middle pipe, and an external pipe fitted onto an external side of the main rubber, wherein the middle pipe is configured to be variable in length thereof.
Abstract:
A hydraulic engine mount, capable of preventing a rattle noise, improving Noise, Vibration, and Harshness (NVH) performance by lowering dynamic characteristics of the hydraulic engine mount in an idling state, and capable of generating a high damping value in a state having a relatively large amount of vibration displacement, includes a case having a hydraulic fluid sealed therein, a nozzle plate having a lower nozzle plate and an upper nozzle plate coupled to an upper portion of the lower nozzle plate, and dividing an inside of the case into an upper fluid chamber and a lower fluid chamber, a first membrane disposed on the upper portion of the lower nozzle plate such that a first edge portion of the first membrane is tightly coupled to the upper portion of the lower nozzle plate, and provided with at least one first communicating hole, a second membrane disposed on a lower portion of the upper nozzle plate such that a second edge portion of the second membrane is tightly coupled to the lower portion of the upper nozzle plate, and provided with at least one second communicating hole, and a separation plate allowing the first membrane and the second membrane to be apart from each other so as to provide a flow space between the first membrane and the second membrane.
Abstract:
A vehicle includes a frame, an engine, and an exhaust system. The frame includes a main frame and a sub-frame movably attached to the main frame. The sub-frame includes an exhaust bracket that includes a hollow collar. The engine includes an engine casing and an exhaust port. The engine is releasably attached to the sub-frame. The exhaust system includes a conduit, a conduit bracket, and a muffler. The conduit includes an upstream end and a downstream end. The upstream end is connected to the exhaust port. The conduit bracket includes a first end and a second end. The first end is attached to the conduit at a location intermediate the upstream end of the conduit and the downstream end of the conduit. The second end of the conduit bracket is movably attached to the hollow collar. The muffler is attached to the downstream end of the conduit.
