Embodiment Construction

[0026] like image 3 , Figure 4 As shown, the balance shaft assembly of the present invention includes a balance shaft 1, a bracket 2, a bearing hub assembly 3 and a bushing 4; wherein the balance shaft 1 is vertically arranged and connected with the bracket 2 through a positioning pin 5, and the bearing hub assembly 3 is connected to the The balance shafts 1 are connected by a sliding fit through bushings 4 . The specific structure is further detailed as follows:

[0027] The balance shaft 1 has support parts 11 at both ends and an eccentric part 12 formed by bending to one side in the middle; four bolt holes 111 are provided in the axial direction of the support parts 11 at both ends, and a positioning hole 112 is provided in the radial direction; the balance shaft 1. The bearing part adopts intermediate frequency surface quenching.

[0028] The brackets 2 are a pair of symmetrical arrangements, respectively supporting the support parts 11 at both ends of the balance sha...

Abstract

The invention relates to a balance shaft assembly, which comprises a balance shaft, a support and bearing hub assemblies. The balance shaft is supported by the support, the bearing hub assemblies are connected to two ends of the balance shaft, and a bearing portion of the balance shaft which is perpendicularly arranged is subjected to medium-frequency surface quenching. The balance shaft assembly is compact in structure and low in cost, bearing capacity of the balance shaft assembly is improved without increasing weight, additional moment of force of the balance shaft assembly in use is reduced, structure is simplified, manufacturing difficulty is lowered, and the service life of the balance shaft assembly is prolonged.

Description

technical field [0001] The invention belongs to the field of vehicles and engineering, and in particular relates to a balance shaft assembly. Background technique [0002] Suspension is one of the main assemblies on a modern car, which elastically connects the frame (or body) to the axle (or wheel). The main task is to transmit all the forces and moments acting between the wheel and the frame (or body), and ease the impact load of the uneven road on the frame (body), and attenuate the vibration of the bearing system caused by the impact load, so as to ensure The normal driving of the vehicle ensures that the wheels have ideal motion characteristics when the road surface is uneven and the load changes, ensuring the handling stability of the car and enabling the car to obtain the ability to drive at high speed. [0003] At present, the suspension includes independent suspension, non-independent suspension and balanced suspension. Among them, the balance suspension is to conn...
