摘要: A multi-member frame assembly for a track system includes a pivot pin defining a pivot axis, a leading frame member pivotally connected to the pivot pin for pivoting about the pivot axis, and a trailing frame member pivotally connected to the pivot pin for pivoting about the pivot axis, the trailing frame member pivoting independently from the leading frame member. A resilient member is pivotally connected to the leading frame member and to the trailing frame member. The resilient member extends generally vertically between the leading frame member and the trailing frame member. A track system having a multi-member frame assembly is also described.

摘要: The invention relates to a tracked vehicle (V1, V2) comprising a vehicle body (20; 120), at least one track assembly (10) and a suspension device (S). Said track assembly (10) is arranged to be supported by said vehicle body (20; 120) by means of said suspension device (S). Said track assembly comprises a track support beam (12) for supporting a plurality of road wheels (16), an endless track (14) being disposed around said road wheels. Said suspension device (S) comprises a leaf spring arrangement (30; 130, 142, 144) having portions transversally arranged relative to the longitudinal extension of the vehicle. Said leaf spring arrangement comprises L-shaped leaf spring members (30; 130), each leaf spring member (30; 130) having a first portion (32; 132) attached to said vehicle body (20; 120), a second portion (34; 134) attached to said track support beam (12) and a transition portion (36; 136) there between, so that compressive and tensile stresses are located to said transition portion (36; 136) for generating a compressive action in said transition portion.

摘要: The present invention relates to a suspension arrangement for a tracked vehicle. The suspension arrangement includes a road wheel arm having a wheel axle portion for supporting a wheel of the vehicle and a pivot axle portion. The road wheel arm is pivotably journalled at the pivot axle portion to a housing that is fixable to the vehicle body. A torsion bar is connected to the pivot axle portion and a torsion tube is arranged to be connected to the vehicle body, with the torsion bar running through the torsion tube and arranged to be connected to the torsion tube. The modulus of elasticity of the torsion tube material is lower than the modulus of elasticity of the torsion bar material such that the maximum suspension travel is increased.

摘要: A snow bike track assembly includes a frame assembly, at least one strut, an endless track, a plurality of top and bottom rollers, a skid rail assembly, a drive assembly, and a swing arm assembly. The frame assembly is configured to connect to a frame of a motorcycle in place of a rear wheel of the motorcycle. The at least one strut is connected to the frame assembly and configured to connect to the motorcycle frame in place of a rear shock of the motorcycle. The plurality of top rollers are mounted to the frame assembly and arranged to support the endless track. The plurality of lower rollers are mounted to the skid rail assembly and arranged to support the endless track. The drive assembly is configured to drive the endless track. The swing arm assembly is coupled between the frame assembly and the skid rail assembly.

摘要: A method for reducing torsional shock of a driving system of an electric vehicle is provided. In the method, torsional torque of a part of the driving system is calculated by applying motor torque to a motor under the condition that a parking gear is engaged and monitoring a motor speed. Reverse torsional torque having the same magnitude as the calculated torsional torque is applied to the part of the driving system when release of the parking gear is requested, and then the parking gear is released to reduce shock caused by torsion of the part of the driving system when the parking gear is released.

摘要: A track assembly includes an elongated main frame supported for pivotal movement on a transverse axis and having opposite end portions supporting a set of end wheels. An endless flexible belt extends around the end wheels and has an upper run and a lower run for engaging the ground. A plurality of longitudinally spaced bogie wheels are positioned below the main frame and engage the lower run of the belt. The bogie wheels are carried by bogie frames supported for vertical movement and also for tilting movement relative to a plane defined by the axes of the end wheels. The bogie frames are urged or biased downwardly against the lower run of the belt by compression members extending from the main frame and preferably in the form of annular rubber spring members.

摘要: A steering system of a vehicle is provided. The steering system adjusts the torsional rigidity of a torsion bar without limitation as to the configuration thereof and performs active control responding to the vehicle state by adjusting steering characteristics by controlling the torsional rigidity of the torsion bar based on the traveling condition, load state or driving mode of the vehicle. The steering system includes an MR assist device, which is coupled to an end portion of the torsion bar and adjusts the rotation and torsional rigidity of the torsion bar using an MR fluid as a working fluid.
