The present invention relates to a disc brake having a brake actuation mechanism, the components of which are mounted in functional cooperation in the brake caliper by means of a rod, in which a brake lever is configured so that the clamping force from the actuator is substantially directed radially to the axis of the brake disc upon brake actuation, and in which the brake lever is further configured to be mounted at different angular positions around the axis of the rod.

A braking system for an autonomous car is provided, including a car body, a pedal, a braking mechanism, a resistance ruler, a driving motor, a connecting member, a first micro switch, a second micro switch, and a control unit. The pedal is pivotally connected to the car body, the braking mechanism is connected to the pedal, and the resistance ruler is disposed on the pedal. The connecting member is connected to the driving motor and the pedal. The control unit is electrically connected to the driving motor, the resistance ruler, the first micro switch, and the second micro switch. When the pedal is in a first position relative to the car body, the pedal contacts and actuates the first micro switch. When the pedal rotates relative to the car body from the first position to a second position, the pedal contacts and actuates the second micro switch.

A motor vehicle having a bulkhead includes: a brake unit, a housing of which is fastenable to the bulkhead of the motor vehicle. An actuating member for actuation of the brake unit extends through the bulkhead. A radial flange is provided on a housing surface facing toward the bulkhead. On the bulkhead, there is provided at least one corresponding fastening element which at least partially engages around the radial flange.

A brake cylinder dust cover is installed on a waterproof brake cylinder. The brake cylinder includes a brake cylinder body and a front cover. A waterproof dust cover assembly is arranged on the front cover. The waterproof dust cover assembly includes a dust cover fixedly connected to the front cover, and a filter felt support and a filter felt pad which are arranged in the dust cover. The filter felt support is connected with the dust cover, and the filter felt pad is fixed on the filter felt support. An outwards extending skirt is arranged at the edge of the dust cover in the axial direction thereof.

A pushrod measurement and verification system for determining a cutback length at which to sever a pushrod extending from a brake chamber so that a slack adjuster is properly mounted in an air brake system. The system includes a measurement member having a body member that includes opposed lower and upper ends, the body member having a thin and planar configuration. The body member defines a plurality of holes adjacent the lower end corresponding to sizes of the slack adjuster to be installed. The measurement member includes a cradle portion mounted to the upper end of the body member, the cradle portion having a bottom wall and a pair of side walls extending upwardly from the bottom wall and defining an open top, the cradle portion configured to cradle a pushrod. A front surface of the cradle portion includes measurement indicia for determining a cutback length of the pushrod.

The present disclosure relates to an axle structure for a motor vehicle, preferably a utility vehicle, for installing a first wheel and a second wheel. The axle structure has a longitudinal axis and defines a vertical reference plane which extends along the longitudinal axis, and the axle structure comprises a first brake cylinder, which preferably has a first central line and is preferably used to brake the first wheel, and a second brake cylinder, which preferably has a second central line and is preferably used to brake the second wheel. The axle structure is characterized in particular in that the first brake cylinder is arranged on one side of the reference plane, and the second brake cylinder is arranged on the other side of the reference plane.

The present invention relates to a disc brake having a brake actuation mechanism, the components of which are mounted in functional cooperation in the brake caliper by means of a rod, in which a brake lever is configured so that the clamping force from the actuator is substantially directed radially to the axis of the brake disc upon brake actuation, and in which the brake lever is further configured to be mounted at different angular positions around the axis of the rod.

An air disc brake system for a heavy-duty vehicle comprising an axle. A spindle is attached to an end portion of the axle. At least a portion of an air disc brake assembly is supported by the spindle. A suspension beam has an axle support portion connectable with the axle. An end portion of the suspension beam is spaced from the axle support portion for attachment with the heavy-duty vehicle. The suspension beam may pivot about the end portion of the suspension beam. An actuator actuates the air disc brake assembly. The actuator has a movable member to actuate the air disc brake assembly. Structure is associated with the suspension beam for supporting at least a portion of the actuator. A surface defines an opening in the suspension beam through which the movable member may extend or that may receive and support a portion of the actuator.

A brake actuator assembly including a pressure plate presenting an opening, a push rod that is coupled to the pressure plate, a diaphragm that is coupled to the pressure plate, and a retainer that engages the push rod. The push rod has an outer surface and at least one protrusion extending outward from the outer surface. The retainer engages the protrusion such that at least a portion of the diaphragm is positioned between the pressure plate and the retainer.

A pressure sensing system of a pneumatic spring brake chamber for a vehicle according to an embodiment of the present disclosure includes a plurality of pressure sensors configured to measure pressure in a pressure chamber formed between a piston and an adapter housing and a service chamber formed between the adapter housing and a diaphragm, a control box electrically connected to the plurality of pressure sensors, and an indicator electrically coupled to the control box, wherein the control box is wired for power supply and output voltage to the plurality of pressure sensors, and the indicator located in a vehicle driver's seat is configured to generate an alarm about an abnormal situation of the pneumatic spring brake chamber for a vehicle based on pressure measurement values in the pressure chamber and the service chamber through the plurality of pressure sensors.
