Axial adjusting device of cross arm

Abstract

The invention relates to a vehicle adjusting device, in particular to an axial adjusting device of a cross arm of a wheel type off-road vehicle. The device comprises supporting seats and a pin roll installed between the supporting seats, wherein the pin roll is connected with the cross arm; the supporting seats are connected with a vehicle body through fixed bolts and are provided with oblong holes for mounting the fixed bolts, and the supporting seats can move along the axial direction of the pin roll; the ends of the supporting seats, far away from the vehicle body, are provided with mounting slots in which round adjusting discs are mounted; the adjusting discs are eccentric discs; rotary centers of the adjusting discs are provided with round holes; the fixed bolts are connected with the vehicle body after passing through the round holes and the oblong holes; the diameters of the fixed bolts, the diameters of the round holes and the diameters of the oblong holes are equal; and the eccentricity of the adjusting discs is not larger than the central distance of the oblong holes. The axial motion of the supporting seats is propelled by the rotation of the adjusting discs in the device, thus, the relative positions of the supporting seats and the cross arm are adjusted to eliminate the axial gap between the supporting seats and the cross arm; and the axial adjusting device is simple in structure and convenient to disassemble and assemble.

Description

Technical field: [0001] The invention relates to a vehicle adjustment device, in particular to an axial adjustment device for a cross arm of a wheeled off-road vehicle. Background technique: [0002] At present, most wheeled off-road vehicles in my country adopt double wishbone independent suspension, and the wishbone is connected to the vehicle body through pin shafts and support seats. Because the driving environment of the off-road vehicle is relatively harsh, the sliding bearing in the support seat is easy to wear, resulting in a gap between the support seat and the cross arm. If the gap is too large, the support seat and the cross arm will have a rigid collision during braking, and the wheel alignment parameters will also be affected, and the ride comfort and stability of the vehicle will be affected to a certain extent. In order to solve the above problems and meet the use requirements of wheeled off-road vehicles, it is necessary to design a cross-arm axial adjustmen...

AI Technical Summary

Problems solved by technology

Due to the harsh driving environment of off-road vehicles, the sliding bearing in the support seat is easy to wear, resulting in a gap between the support seat and the cross arm

If the gap is too large, the support seat and the cross arm will have a rigid impact during braking, and the wheel alignment parameters will also be affected, and the ride comfort and stability of the vehicle will be affected to a certain extent.
