The invention relates to a power transmission of a turning-track track-laying vehicle. The track-laying vehicle comprises such a closed-loop type track belt (10) arranged between end rolls or similar (11, 12) in such a way that one edge of the track belt can be stretched and the other edge of the track belt contracted in order to make the vehicle execute a turn. The vehicle comprises a motor (26), a traction sprocket or sprockets (30), and power transmission equipment between the traction sprocket or sprockets (30) and the motor (26). The drive sprocket or sprockets (30) are positioned above the top run of the track belt (10), preferably sideways in its middle range. In the traction sprocket or sprockets (30) there are drive cogs (32) or similar, which drive cogs (32) are in driving contact with the openings (40), grooves or similar of the track belt, so that the traction force can be transmitted from the traction sprocket or sprockets (30) to the track belt (10). The drive fit between the upper run of the track belt (10) and the traction sprocket or sprockets (30), such as a cog fit, is such that the fit lets the traction sprocket or sprockets (30) and the track belt (10) to interactively take such a driving position, which is mainly determined by the curvature of the the track belt.

The invention relates to an intelligent control system for current distribution in a vehicle. The current distribution and communication transmission are handled by a central unit which is divided into structurally discrete junction modules (2), each of which connects to its own cable branch (4). Each junction module controls independently the power supply and communication transmission for the cable branch (4) attached thereto. The central unit is further provided with elements for the transmission and reception of communication between the junction modules (2). The intelligence required for the load-specific operating control is decentralized to connecting sockets (3) present in the cable branches (4).

This invention relates to a junction between an intelligent contact terminal (3) and a cable (1, 2), said junction comprising connector pins (4) extending from the contact terminal (3), penetrating into a cable insulation sheath (1) and piercing flat wires (2) included in the cable and provided with lip portions (10) pressing against the lateral faces of the pins. In order to provide a secure contact, the pins (4) are slightly conical or tapered at least within the region of said lip portions (10). By designing the flat wire as a multilayer wire, the lip portions (10) of the wire layers together can be brought to provide an increased contact area. In addition, the multilayer wire (2) is penetrable with a lesser application of force if the cable is provided with preliminary holes for the pins (4).

The present invention relates to improving the stability of a turning-track track-laying vehicle such as a snowmobile. The vehicle comprises such a track belt (10), whose one edge can be stretched and whose other edge can be contracted by turning the end roll (14) or rolls (14, 15) which guide the track belt (10) so that the track belt (10) can be bent to a curved position in order to steer the vehicle. The bottom run of the track belt (10) loop is, in front of the crosswise gravity center plane (A--A) seen in the principal driving direction (E) of vehicle, pressed or weighted against the driving surface, particularly against soft snow (L--L), in such a way that, due to and in the region of said weighting, such a limited area (P33) of surface pressure higher than the average is created in which the maximum surface pressure (pmax, p2) is substantially higher than the average surface pressure (p1) in the rear section of the bottom run of the track belt.

The invention relates to an intelligent current distribution system and a method for manufacturing the same. The current distribution system is particularly intended for vehicles. In the method, a current distribution cable (3) is fitted with intelligent connecting sockets (1, 2), which are provided with output pins (8) for supplying current to loads to be connected to the system and with switches (18a) for distributing current to the output pins (8) as well as with control electronics (19) for controlling the switches (18a) on the basis of control messages received from a message communication bus (17) of the cable (3) or from a socket input connector (10). Prior to or after connecting the randomly selected sockets (1, 2) to the cable (3), the control electronics (19) of each socket is programmed with individual behave programs (26), which are preordained on the basis of the location of the socket (1, 2) on the table. The sockets (1, 2) of the system communicate with each other directly via the bus, without intermediation of a central control unit.

The invention relates to an intelligent current distribution system for vehicles and a method for manufacturing the system. In the system, the current is distributed to loads through intelligent connecting sockets (1). The sockets are mounted in desired locations on a cable (2), whose message communication bus (11) or a socket input-connector (7) is used to deliver control commands to control electronics (14-17) controlling operation of the socket. The control electronics include a basic program memory (16), in which are stored operating instruction programs for all necessary functions of several sockets in the system. Thus, any socket can be randomly located at least within a limited portion of the current distribution system. The socket is modified for individual operation during or after installation of the socket. Therefore, in the parameter program memory (17) there are stored parameter programs, which control individually the functions of a socket and which are predetermined specifically for each socket. The parameter programs control only a limited number of the function control programs of the basic program memory (16) to make only predetermined function control selections for said individual operation.
