Land vehicles and methods of operating land vehicles are disclosed. A land vehicle includes a frame structure, a plurality of wheels, and a brake system. The frame structure includes a front cage that at least partially defines an operator cabin and a rear compartment positioned rearward of the front cage in a longitudinal direction. The plurality of wheels are supported by the frame structure. Each of plurality of wheels is sized to permit direct integration of an electric motor therein.

A method of controlling a brake system that includes a motor and an actuator. The method includes moving the actuator towards a retracted position; activating a timer; monitoring a motor characteristic of the motor and monitoring the timer; and determining the actuator has reached the retracted position after the timer meets or exceeds a predetermined time threshold before the motor characteristic has reached or exceeded a predetermined motor characteristic threshold.

A disc brake according to an embodiment of the present disclosure includes a cylinder body and a bracket assembly. The bracket assembly is disposed in a space in the cylinder body. The cylinder body and the bracket assembly are fastened to each other by fastening members.

Provided is an electric brake device including one caliper including at least two electric mechanisms each configured to apply a braking force to a vehicle and to maintain the braking force. The at least two electric mechanisms are to be driven by one drive circuit output, that is, one output from one drive circuit. In this manner, for example, even when it is required to control a large number of electric mechanisms as in a case in which the electric brake device is applied to a twin-bore caliper, the number of drive circuits for driving the electric mechanisms can be reduced, thereby being capable of reducing cost.

A method for actuating a parking brake system of a vehicle with at least three brake calipers associated with one or more axles of the vehicle is described. The method may include the following steps: providing at least one detection device for detecting the vehicle status, acquiring a value of the vehicle status with the detection device, comparing the detected value with a reference value of the vehicle status, and actuating two brake calipers of the at least three brake calipers if the detected value is lower than the reference value or actuating all the at least three brake calipers if the detected value is equal to or greater than the reference value.

A land vehicle includes a frame structure, a plurality of wheels supported by the frame structure, and a body supported by the frame structure. The frame structure includes an operator cage that at least partially defines an operator cabin and a rear compartment positioned rearward of the operator cage in a longitudinal direction. The body includes a first sidewall arranged on one side of the vehicle and a second sidewall arranged on another side of the vehicle opposite the first sidewall.

A method of making a brake assembly. The method may include providing a brake pad carrier, an air operated brake actuator suitable for attaching to the brake pad carrier, and a hydraulically operated brake actuator suitable for attaching to the brake pad carrier, and attaching one of the air operated brake actuator and hydraulically operated brake actuator to the brake pad carrier to provide a brake assembly.

A brake caliper has a fixed seat. The fixed seat has a first brake lining and a second brake lining. The fixed seat further has a first piston and a second piston that can be pushed by hydraulic oil. A movable seat is slidably disposed on the fixed seat. The movable seat has a link portion that can link the first brake lining and a drive unit that can push the second piston mechanically. The first piston and the second piston can be pushed hydraulically to drive the first brake lining and the second brake lining for braking. The drive unit pushes the second piston to drive the second brake lining, and pushes the movable seat to drive the first brake lining for braking.

Provided in a device for activating a wheel brake of a vehicle, having a tensioning installation which has a spindle drive, are two electric motors, the first electric motor by way of a first gear mechanism acting bi-directionally on the spindle drive. In order for the position of the tensioning installation, once attained, to be fixed in a parking brake, a second electric motor by way of a second gear mechanism, which has a self-locking worm gear mechanism and by way of at least one releasable coupling that acts uni-directionally in the activating direction, is coupled to the spindle drive. The coupling is composed of a cam on an output shaft of the first gear mechanism, and a pin on an output element of the worm gear mechanism. Since the cam cannot be reversed beyond the pin, a latching position of the tensioning installation is defined in this way.

A brake system that includes a brake caliper comprising an inboard side and an outboard side, the inboard side of the brake caliper includes one or more brake pistons and the outboard side of the brake caliper comprises one or more brake pistons, and a brake pad comprising a first pad section and a second pad section. During a service brake apply, both of the first pad section and the second pad section are moved against a braking surface to create a clamping force. During a parking brake apply, only one of the first pad section and the second pad section is moved against the braking surface to create a clamping force. The first pad section comprises a friction material having a coefficient of friction that is different than a coefficient of friction of the second pad section.
