Embodiment Construction

[0016] 1 and 2 schematically show the front area of ​​a motor vehicle trailer (1) and its drawbar (2). The vehicle trailer (1) has a one- or two-axle undercarriage or chassis and a rigid drawbar (2), the drawbar head of which is only shown schematically in the drawing. The preferably rigid drawbar ( 2 ) can be designed in any desired manner, for example as a V-shaped drawbar or as a tubular drawbar. A trailer coupling (3) with a coupling mechanism is provided at the front end of the tow bar, via which the vehicle trailer (1) can be connected to a ball joint or other type of coupling on the tractor.

[0017] The braking device (4) of the motor vehicle trailer (1) comprises wheel brakes (not shown) on the wheels, which can be operated via a brake lever (11). The brake lever (11) is to be understood as any actuating mechanism, which can also be, for example, a cable drive, a hydraulic force transmission or the like.

[0018] The brake device (4) comprises at least one hand brak...

Abstract

The invention relates to a handbrake lever (14) for brake devices (4) of vehicle trailers (1). The pivotable handbrake lever (14) has a variable length and a telescopic grip part (21) having a variable extending length ?L. The grip part (21) has a positive guidance means (27) which controls the extending length ?L as a function of the rotational position of the handbrake lever (14) in such a way that the extending length ?L is at a maximum in the actuating position of the handbrake lever (14) and at a minimum in the release position.

Description

technical field [0001] The invention relates to a hand brake lever for a brake device of an automobile trailer. Background technique [0002] Such handbrake levers are known from DE10237212A1 and DE69405784T2. The handbrake lever, which is rotatably mounted on the housing of the brake system of the motor vehicle trailer, has a variable length which is smaller in the released position than in the actuated position. The handbrake lever has a telescopic grip with a variable extension Δl. The grip is mounted displaceably on the base body of the handbrake lever and can be moved against the force of a return spring. The actual length of protrusion entered depends on the type of manual operation. In order to achieve the maximum extension Δl in the operating position, the handle must be pulled upwards against the force of the return spring, which is problematic in terms of handling and ergonomics. Spring loading also makes the extension Δl indeterminate and depends on the pulli...
