Problems solved by technology

Existing devices for measuring the chassis geometry of trucks and passenger cars are very expensive and therefore do not enter the market
Of course the measurement of the chassis geometry parameters is imprecise when the wheel is stationary due to the impact of the wheel and the tire markings, and the current requirements in terms of measurement accuracy have become inapplicable

Embodiment Construction

[0023] From figure 1 As can be clearly seen in FIG. 2 , the device has four wheel receptacles 1 , of which two wheel receptacles 1 a are assigned to the front axle of the vehicle and two wheel receptacles 1 b are assigned to the rear axle of the vehicle. For vehicles with two steered front axles, correspondingly two further wheel mounts 1 a are provided for supporting the other steered front axle. The wheel receptacle 1 can also be adjusted transversely to the longitudinal axis of the vehicle in order to allow adjustment to different wheel bases.

[0024] Wheel receiving mechanism 1 in figure 1 The center is in the form of a steel strip, which is rotatably mounted in a support 2 and equipped with a drive 3 . Since each belt 1 has its own drive, the belts 1 as well as the vehicle wheels placed on the different belts can be rotated independently.

[0025] A turntable 4 is mounted on each belt 1 for the actual support of the steering wheels of the vehicle. Since the turntable...

Abstract

The invention relates to a device for the measurement of the undercarriage geometry of vehicles, in particular buses and lorries. The device comprises wheel receiving means which can be translationally displaced in the direction of the longitudinal axis of the vehicle. The front and / or rear wheels of the motor vehicle can be positioned on the wheel receiving means, and the wheel receiving means are arranged in a horizontal plane. The invention also comprises measuring systems. In order to create a device for the measurement of undercarriage geometry, in particular of buses and lorries, which allows a cost-efficient, quick, and precise measurement of the undercarriage geometry on rotating wheels, the invention suggests that at least four wheel receiving means which can be displaced in the direction of the longitudinal axis of the vehicle are provided, and at least one rotary disk for receiving a wheel is arranged on each wheel receiving means. Thr rotary disk can move in a straight line on the upper side of the belt with the movement of the belt. The measurement element arranged at the side of the wheel receiving means is acted as a measurement system.

Description

technical field [0001] The invention relates to a device for measuring chassis geometry parameters of vehicles, especially passenger cars and trucks. Background technique [0002] Known from EP 0 594 163 B1 is a device for measuring geometrical parameters on the axle of a vehicle as the wheels rotate, which has at least two drivable assemblies mounted at a distance from the track width of the vehicle, the front and rear wheels of the vehicle Wheels can be placed on assemblies and each assembly is mounted on a level opposite to a base frame, as an assembly for supporting wheels on at least one axle, with drivable, endless and in the form of conveyor belts belt and measuring system. Here, there is a base body supporting the strips, which is supported on a base plate, with closable centering devices for limiting the degree of freedom of the base body relative to the base plate. [0003] For trucks and passenger cars, due to their high weight and varying number of axles and wh...
