Abstract
A third drum mechanism of a slide type automobile drum experiment bench is composed of a third drum assembly, guide limit supports and a cylinder (10). The third drum assembly is composed of an upper arc plate (1), a lower arc plate (1), a left lateral plate (2), a right lateral plate (2) and a third expansion cylinder (3), the guide limit supports are symmetrically arranged on the left and the right and are respectively composed of a bearing, a bearing seat (5), a transverse beam (6), an idler wheel support (7), a guide wheel (8) and a limit wheel (9). Tracks at two ends of the third drum assembly are supported on the guide limit supports and are capable of rotating around the outside of the drum circle vertically under the effect of the cylinder (10). When the third drum mechanism is tested, the third drum mechanism rises to enable a third drum to be contacted with a tire to limit the horizontal position of the tire and have the effect of location and safety protection. When the test is finished, the third drum assembly is retreated downwards to facilitate passing in and out of automobiles.

Said the 3rd drum assembly and guide and limit support is characterized in that, lower curved plate and rotary drum (4) have certain interval in the 3rd drum assembly, avoid movement interference; Last lower curved plate (1) is the isocentric circular arc of rotary drum (4), and the 3rd drum assembly is supported on the position-limited wheel (9) and angle sheave (8) of guide and limit support through the circular arc slide rail, and the axis of the drum (4) that rotates moves up and down, and is moved by position-limited wheel (9) limit axial; Position-limited wheel (9) and angle sheave (8) are installed on the rolling wheel support (7) through bearing pin; Rolling wheel support (7) is welded on the crossbeam (6), and crossbeam links to each other with testing table.
Said a kind of slide rail type automobile drum dynamometer the 3rd rotary drum mechanism can be used on automobile brake, the driveability testing table; Driving on the testing table, the 3rd rotary drum mechanism is positioned at rotary drum (4) the place ahead; On brake tester, be positioned at rotary drum (4) rear; On the drive brake multi-function test stand, need two covers the 3rd rotary drum mechanism, be positioned at former and later two directions of rotary drum (4).Preceding the 3rd rotary drum of on-test (3) is in the below of rotary drum (4) top, horizontal tangent plane; During test, sail automobile into testing table earlier, and wheel is parked in rotary drum (4) top; Start air lift pump, under the promotion of cylinder (10) elongation, the 3rd drum assembly moves up and down along the guide and limit support; When the 3rd rotary drum (3) contact vehicle tyre, the cylinder stop motion limits its height, and makes an experiment.After the off-test, cylinder (10) retraction drive under, fall the 3rd rotary drum and support arc plate and the 3rd rotary drum (3), and vehicle is sailed out of testing table.
Description of drawings
Accompanying drawing is a kind of slide rail type automobile drum dynamometer the 3rd a rotary drum mechanism, and among the figure, lower curved plate, (2) left side plate, (3) the 3rd cylinders, (4) rotary drum, (5) bearing and bearing seat, (6) crossbeam, (7) rolling wheel support, (8) angle sheave, (9) position-limited wheel, (10) cylinder are gone up in (1).
Embodiment
Specify the present invention below in conjunction with accompanying drawing.
