The present invention relates to an actuator device (1) for a hydraulic brake/clutch actuation system of a motorcycle, comprising a secondary support structure (21) provided with at least a secondary chamber (211), a secondary piston (22) arranged within the secondary support structure (21) and able to be moved within the secondary chamber (211) between a secondary resting position and a secondary working position, and vice versa, a secondary actuating pin (23) solidly coupled to the secondary piston (22) and arranged outside the secondary support structure (21), wherein the free end (231) of the secondary actuating pin (23) is distanced from the secondary support structure (21) when the secondary piston (22) is in the secondary working position and is arranged at the secondary support structure (21) when the secondary piston (22) is in the secondary resting position, a secondary elastic element (24) arranged within the secondary support structure (21) and able to maintain the secondary piston (22) in the secondary working position when not actuated, wherein the primary chamber (111) and the secondary chamber (211) are arranged in fluid communication so that the secondary piston (22) is arranged from the secondary working position to the secondary resting position by the movement of a hydraulic fluid when the primary piston (12) is actuated from the primary resting position to the primary working position, and wherein the secondary elastic element (24) is arranged within the secondary chamber (211).

The present disclosure relates to a method for producing a brake force device for a vehicle brake system, in which a housing is produced, wherein a recess is formed in the housing, wherein a piston device is arranged in the recess, wherein the piston device is movably guided in the axial direction of a longitudinal axis of the recess and along a specified maximum stroke path, and the length of the maximum stroke path of the piston device is modified for different embodiments of the brake force device. In order to improve and/or to simplify the implementation of different embodiments of the brake force device.

A brake lever assembly includes a body, a seat and a pin. The body is connected to the seat and includes an outer surface which is engaged with an inner surface of the seat so that the body cannot rotate relative to the seat. The seat is connected to a brake lever and a handlebar. The body is connected to an adapter which is connected with a hydraulic oil pipe. A piston is located in the body and activated by the brake lever. The pin extends through the seat and the body to prevent the body from dropping from the receiving hole axially. The brake lever assembly is easily installed to the handlebar.

A hydraulic device is basically provided with a cylinder housing and a reservoir. The cylinder housing includes a cylinder bore. The reservoir is configured to be in fluid communication with the cylinder bore. The reservoir includes a reservoir tank and a lid slidably attached to the reservoir tank.

A piston assembly is provided for a human-powered vehicle. The piston assembly includes a main body and a primary seal. The main body is configured to be movable from a rest position to an actuated position along an actuation direction in a cylinder bore. The primary seal includes a primary seal body arranged on the main body. The primary seal body is made of a resin material. The main body includes a first part and a second part. The first part is at least partly arranged upstream of the primary seal with respect to the actuation direction. The second part is coupled to the first part to be at least partly arranged downstream of the primary seal with respect to the actuation direction. The at least one of the first part and the second part includes a support portion supporting the primary seal.

A snow vehicle having a combined brake and clutch handle is herein disclosed. Further, the snow vehicle can include a controller for managing operation of the snow vehicle, including shifting and engine management regiments, which can be selected by the operator depending upon operator preferences. Additionally, the snow vehicle can include an engine cooling heat exchanger for cooling liquid which is circulated through the engine.

A brake system for a vehicle such as a bicycle is disclosed. The brake system may comprise an improved master cylinder assembly configured (e.g. manufactured/produced, assembled, etc.) so that a setting and/or adjustment of the brake stroke and/or lever action/actuation can be provided by any one independent mechanism (e.g. without any other adjustment mechanism) or by a combination of adjustment mechanisms (e.g. in a combination with one or more adjustment mechanism); operation of a mechanism for setting and/or adjusting the brake stroke may comprise a feature configured to engage a pushrod (e.g. by direct action on the pushrod or a feature of the pushrod or by indirect action through a link, adjuster, etc. configured to engage the pushrod). The master cylinder assembly may be configured to be set and/or adjusted/tuned within the indicated range to provide an intended performance and/or “feel” for the operator at the brake lever.
