Embodiment Construction

[0016] Examples of chassis dynamometers are Figure 1~5 As shown: four dynamometer units are included, and the four dynamometer units form two pairs arranged front and back, and each pair of dynamometer units includes two dynamometer units 6 arranged left and right. The platform seat of the chassis dynamometer has accommodating grooves 7, and each dynamometer unit 6 is placed in the corresponding accommodating grooves 7, respectively. The chassis dynamometer also includes a fixing device used to prevent the position of the vehicle from changing during the test. The fixing device includes a hinged frame 5 hinged in the sinker on the rear side of the dynamometer unit. The hinged frame 5 is provided with a hook 3. During the test, The car can be fixed by arranging a stay rope between the hinged frame and the car to prevent the car from moving forward, and the hinged frame is not in use. Can be turned over into sinker 4.

Abstract

The invention relates to a chassis dynamometer, which comprises at least one dynamometer unit. The dynamometer unit comprises a bearing support. The bearing support is provided with a driven wheel anda driving wheel driven by a driving mechanism. The driving wheel is connected with a dynamometer. The driving wheel and the driven wheel are wrapped by an endless driving belt in friction rolling fitwith a corresponding wheel of a vehicle. The lower side of the upper endless support belt part is provided with a support body fixed with respect to the bearing support. The endless support belt hasthe following two setting forms: firstly, the endless support belt is a flexible belt, and the support body is a support plate in support cooperation with the upper endless support belt part; and secondly, the endless support belt is a rigid belt, and the endless support belt comprises a plurality of rigid belt sections hinged from the head to tail in sequence, and the support body is the supportplate in support cooperation with the upper endless support belt part or at least two support bars in left-right interval arrangement. The chassis dynamometer solves the problem that it is easier forthe endless driving belt to sink and deform in the prior art.

Description

technical field [0001] The invention relates to a chassis dynamometer and a dynamometer unit thereof in the field of automobile testing. Background technique [0002] Chassis dynamometer is the key testing equipment for vehicle dynamic performance testing, and chassis dynamometer can be used to test vehicle dynamic performance. Existing chassis dynamometers such as "a belt transmission device for chassis dynamometer" disclosed in Chinese patent CN203051647U, the belt transmission device includes a driving wheel and a driven wheel arranged front and rear, and the driving wheel and the driven wheel are wound on the useful The wedge-shaped belt that is frictionally and rollingly matched with the corresponding wheel is the endless transmission belt. During the test, the test is realized by the wedge-shaped belt and the wheel transmission. The existing belt transmission device has the following problems. The use of the transmission belt structure itself is to more realistically ...
