Abstract
The utility model relates to a shock absorber servo type driving cab rear suspension device, which comprises a cross beam, a cross beam connecting plate, an upper supporting seat, a lower supporting seat, and a shock absorber, and is characterized in that the two cross beam connecting plates are mounted at the two ends of the cross beam symmetrically, a hydraulic lock is mounted at the lower end of every cross beam connecting plate, a lower supporting seat is connected to the lower end of each cross beam connecting plate, coil springs are sleeved on the cylinder type shock absorber to form coil spring shock absorber assemblies, the two sets of coil spring shock absorber assemblies are arranged vertically on the two sides of the cross beam, the lower end of the coil spring shock absorber assembly is connected with the lock plunger of the hydraulic lock, the upper end thereof is connected with the upper supporting seat, and rubber guide wheels are arranged at the two ends of the cross beam. The utility model has the advantages that the structure of the rear suspension device in the traditional driving cab is simplified, the mounting method thereof is redesigned, thereby reducing the required cost and weight, saving greatly the space and facilitating the assembly.
Description
Technical field:
The utility model relates to a kind of bumper trailing type operator's compartment rear suspension device.
Background technology:
The most steel spring bumper structures that adopt of present domestic truck cap rear suspension device, the part kind is many, assemble loaded down with trivial details, cost and weight height, it is bigger to take up room, and is unfavorable for the layout of other big parts.
Summary of the invention:
The purpose of this utility model is in order to solve the problem that above-mentioned prior art exists, and provides that a kind of structure is simple and direct, cost is low, in light weight, the bumper trailing type operator's compartment rear suspension device that occupies little space.
The purpose of this utility model is realized by following mode:
The utility model comprises crossbeam, cross-beam connecting plate, upper bracket, undersetting, bumper, it is characterized in that: two cross-beam connecting plates are installed in the two ends of crossbeam symmetrically, in the lower end of each cross-beam connecting plate a hydraulic lock is installed respectively, the lower end of each cross-beam connecting plate connects a undersetting, bumper is a telescopic shock absorber, be with coil spring on the bumper and constitute the helical spring shock absorber assembly, two cover helical spring shock absorber assemblies are arranged vertically in the crossbeam both sides, the lower end of helical spring shock absorber assembly connects the locking bolt of hydraulic lock, and be connected with hydraulic lock by locking bolt, the upper end connects upper bracket, at the crossbeam two ends rubber track adjusting wheel is housed.
The beneficial effects of the utility model are: simplified the structure of traditional operator's compartment rear suspension device, the mounting means of redesign reduces its required cost and weight, and has saved the space greatly, assembles also comparatively simple.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
The specific embodiment:
With reference to accompanying drawing, the utility model comprises crossbeam 3, cross-beam connecting plate 5, upper bracket 1, undersetting 4, bumper 7, two cross-beam connecting plates 5 are installed in the two ends of crossbeam 3 symmetrically, in the lower end of each cross-beam connecting plate 5 hydraulic lock 6 is installed respectively, the lower end of each cross-beam connecting plate 5 connects a undersetting 4, bumper 7 is a telescopic shock absorber, be with coil spring 8 on the bumper 7 and constitute the helical spring shock absorber assembly, two cover helical spring shock absorber assemblies are arranged vertically in crossbeam 3 both sides, the lower end of helical spring shock absorber assembly connects the locking bolt 9 of hydraulic lock 6, and be connected with hydraulic lock 6 by locking bolt 9, the upper end connects upper bracket 1, at crossbeam 3 two ends rotating rubber track adjusting wheel 2 is housed, 1 position-limiting action of 2 pairs of upper brackets of rubber track adjusting wheel, thereby realize position-limiting action, and rubber track adjusting wheel 2 can play the guiding role to helical spring shock absorber assembly and upper bracket 1 when the operator's compartment lifting to helical spring shock absorber assembly and operator's compartment; Hydraulic lock 6 has a direction recess, can play effect spacing and guiding when operator's compartment falls.The utility model at the mounting means on the vehicle is: upper bracket 1 is fixed on the operator's compartment of vehicle, and crossbeam 3 is fixed on the left-right longeron of vehicle by cross-beam connecting plate 5, undersetting 4.When the operator's compartment lifting, hydraulic lock 6 is opened automatically, the hydraulic lock locking bolt 9 that is connected on the helical spring shock absorber assembly breaks away from hydraulic lock 6, helical spring shock absorber assembly and upper bracket 1 rise with operator's compartment, when operator's compartment falls, the effect of the direction recess by rubber track adjusting wheel 2 and hydraulic lock 6 can guarantee that locking bolt 9 on the helical spring shock absorber assembly falls back in the hydraulic lock 6 hydraulic lock 6 automatic lockings accurately.On bumper trailing type operator's compartment rear suspension device of the present utility model warning device can also be installed, not have complete locking as operator's compartment, system's auto alarm is reminded the chaufeur inspection.
