Abstract
The utility model provides a kind of lateral random loading test mechanism of commercial vehicle front axle assembly, is laterally loaded fork, linear actuator etc. by simulation wheel hub, wheel hub connecting plate, the lateral loading arm of wheel center grounding point, wheel center grounding point and is formed；The lateral loading arm of wheel center grounding point is simulated wheel hub by load fork, wheel hub connecting plate etc. and is loaded on knuckle, and simulation wheel hub is provided with real vehicle bearing；Lateral load(ing) point had both been protected in this way be in wheel center grounding point always, while also reducing and being influenced each other with wheel center grounding point longitudinal loading using two load when a loading arm；Mechanism is ingenious in design, and longitudinally, laterally load interferes wheel center when efficiently solving the problems, such as to carry out front axle assembly bench test, improves the precision of bench test.
Description
Technical field
The utility model belongs to auto parts and components bench test technical field, be related to a kind of commercial vehicle front axle assembly laterally with
Machine load test mechanism is mainly used for carrying out the lateral random loading of wheel center grounding point of front axle assembly bench test.
Background technique
Front axle assembly is the critical component in commercial vehicle chassis steering system, and the knuckle that can use in assembly makes wheel
It deflects certain angle and completes motor turning function.It is longitudinally carried other than bearing vertical load, also subject to wheel center grounding point
Lotus, wheel center longitudinal loading and wheel center grounding point lateral load.
Currently, for front axle assembly bench test mainly unidirectionally loaded with constant amplitude based on, and it is complicated under real vehicle state
Stress condition difference is larger, causes the failure mode of rack and considered repealed form inconsistent, can not really play inspection product
Effect, existing parts thereof manufacturer, the country starts to carry out the bench test design of the multidirectional random loading of front axle assembly,
Wheel center grounding point longitudinal loading, lateral load use common loading arm, and effect is not satisfactory.Therefore it is a set of reasonable to design
The lateral loading mechanism of wheel center grounding point be the multidirectional random loading gantry designs of front axle assembly emphasis.
Summary of the invention
The utility model provides a kind of commercial vehicle front axle to overcome the problems, such as that existing front axle assembly bench test exists
The lateral random loading test mechanism of assembly.
The utility model adopts the following technical scheme that realization:
A kind of lateral random loading test mechanism of commercial vehicle front axle assembly, which is characterized in that front axle assembly to be tested is logical
It crosses two front axle fixed blocks to be fixed on two horizontally disposed front axle hold-down supports, front axle fixed block can be around front axle hold-down support
Axis rotation, the left end of front axle assembly and right end be mounted on a simulation wheel hub and a knuckle, simulation wheel hub and turns
It is connected to front axle assembly end by real vehicle use state to section, simulation wheel hub is provided with the bearing that real vehicle uses, and wheel center connects
The lateral loading arm top in place is fixedly connected by wheel hub connecting plate with simulation wheel hub, and linear actuator passes through wheel as moved end
Centre-point earth point laterally loads fork and pin shaft and the lateral loading arm lower end of wheel center grounding point is hinged, and linear actuator is along wheel
Centre-point earth point is laterally disposed and fixing end of linear actuator is hinged on lateral linear actuator support by spherical hinge.
Compared with prior art the beneficial effects of the present invention are:
The utility model provides a kind of novel lateral random loading test mechanism of commercial vehicle front axle assembly, mechanism master
Fork, line are laterally loaded by simulation wheel hub, wheel hub connecting plate, the lateral loading arm of wheel center grounding point, wheel center grounding point
Property the composition such as actuator.The lateral loading arm of wheel center grounding point is by load fork, wheel hub connecting plate etc. through simulation wheel hub load
Onto knuckle, simulation wheel hub is provided with real vehicle bearing.Lateral load(ing) point had both been protected in this way and has been in wheel center grounding point always, together
When also reduce and influenced each other with wheel center grounding point longitudinal loading using two load when a loading arm.Mechanism design
Ingenious, longitudinally, laterally load interferes wheel center when efficiently solving the problems, such as to carry out front axle assembly bench test, mentions
The high precision of bench test.

Specific embodiment
The present invention is explained in detail with reference to the accompanying drawing:
The lateral random loading test mechanism of a kind of commercial vehicle front axle assembly described in the utility model, as shown in Figure 1, to be measured
The front axle assembly 2 of examination is fixed on two horizontally disposed front axle hold-down supports 3 by two front axle fixed blocks 1, and front axle is fixed
Block 1 can be rotated around the axis of front axle hold-down support 3, and the left end of front axle assembly 2 and right end are mounted on a simulation wheel hub 7 and one
A knuckle 6, lateral 10 top of loading arm of wheel center grounding point are fixedly connected by wheel hub connecting plate 8 with simulation wheel hub 7, mould
Quasi- wheel hub 7 is connect with the knuckle 6 of front axle assembly 2 by real vehicle state, and the moved end of making of linear actuator 5 is grounded by wheel center
The lateral load fork 11 of point and pin shaft 9 and lateral 10 lower end of loading arm of wheel center grounding point are hinged, and linear actuator 5 is along wheel
Heart grounding point is laterally disposed and the fixing end of linear actuator 5 is fixed on lateral linear actuator support 4 by spherical hinge.Examination
During testing, two linear actuators 5 are all made of load control mode, by coordinated control to front axle assembly 2 to be tested, mould
Quasi- wheel hub 7 and knuckle 6 apply the lateral random load of wheel center grounding point.
