Problems solved by technology

[0012] However, the use of the auxiliary roller unit can cause reverse motion of the vehicle during the brake test when the braking force is gradually increased
[0013] This inevitably leads to imprecision in the tests performed, since the measured forces are underestimated and thus untrue and unreliable

Embodiment Construction

[0023] With particular reference to these figures, shown generally at 1 is an apparatus for a brake system test bench of a vehicle, in particular a brake system test bench usable for a four-wheel drive vehicle.

[0024] More specifically, the apparatus 1 can be used to perform brake tests on vehicles with permanent four-wheel drive, that is, those vehicles with all four wheels engaged at all times, with all four wheels Drives do not engage / disengage as desired.

[0025] The device 1 comprises a supporting frame 2 capable of resting on the ground and resting and rotating means 3 supported by the frame 2, said resting and swiveling means 3 being adapted to rest a wheel R of a vehicle and adapted to allow the wheel R to rest on the brake system of the vehicle Free spins during the test.

[0026] With reference to the specific embodiment shown in the accompanying drawings, the frame 2 has a substantially rectangular shape, and corresponding to parts substantially opposite to each...

Abstract

The equipment for test stands of the braking system of vehicles, in particular for four-wheel drive vehicles, includes a bearing frame having a resting and rotation apparatus for a wheel of a vehicle, suitable for resting the wheel and for allowing the free rotation of the wheel during a test of the braking system of the vehicle, and a containment element associated with the frame and suitable for engaging onto a portion of the wheel to retain the wheel onto the resting and rotation apparatus during the test of the braking system of the vehicle.

Description

technical field [0001] The invention relates to a device for a vehicle braking system test bench, in particular for testing the braking system of a four-wheel drive vehicle. Background technique [0002] The use of so-called roller test stands in workshops for testing vehicle brake systems is already known. [0003] Specifically, such test benches are generally used during the overhaul of motor vehicles, commercial vehicles, mopeds and motorcycles with two, three or four wheels to measure and test Braking force on each wheel. [0004] Test benches of the known type generally comprise a pair of seats, arranged side by side and at a distance from each other, designed to accommodate and control the individual wheels during the testing phase of the braking system. [0005] Specifically, during the overhaul of a traditional two-, three- or four-wheeled vehicle, the vehicle may be placed on a test stand with one or both wheels positioned in seats. [0006] However, these known ...
