Abstract:
A vehicle cab suspension (10) is provided with a body (12) having a mounting member (18) positioned at least partially within the body (12). One or more resilient members (20,22) connect the body (12) to the mounting member (18) and are placed in a compressed condition between the body (12) and the mounting member (18) when the vehicle cab suspension is in an unloaded condition. The body (12) may be formed of first and second body pieces (14, 16), each of which may be provided with upper and/or lower projections (38, 40) to restrict movement of the resilient members (20, 22) during use.
Abstract:
A suspension system for a driver's compartment on a vehicle chassis is provided, comprising a mounting arrangement for mounting the driver's compartment on the vehicle chassis including at least two pneumatic springs to be arranged along a lateral side of driver's compartment and coupled between the driver's compartment and the vehicle chassis. For each pneumatic spring a pressure sensor and a deflection sensor are provided, measuring a spring pressure and spring height respectively. For each pneumatic spring a valve device is communicatively coupled to a pressure supply; a vent and a respective pneumatic spring. A continuously variable force setpoint can be set that defines a pressure difference between an inlet and outlet terminal and a controller is provided for setting a force setpoint of the valve by powering the actuator based on a reference derived from a electronic vehicle control system (ECU) irrespective of mass flow and temperature.

Also provided is a method for minimizing cavitation of a common magnetorheological device, comprising providing an MR fluid within the device with a pressure of at least 100psi. The device as provided minimizes cavitation in the device, and can be broadly used in the railway vehicle suspension system with excellent performance.
Abstract:
The invention relates to a driver's cab of a utility vehicle, which is supported on a frame (1) by means of at least one support (8; 9) of said cab, aided by suspension struts (10; 20) and a pair of oscillating arms (11; 21) on bearings (15; 16; 25; 26) that are fixed to the frame, whereby one end of the oscillating arms is connected in an articulated manner to the support. To position the roll centre in the centre of gravity; a) the other end of the respective oscillating arms (11; 21) is supported on a first articulation point (32, 33; 32; 42) of a first deviation lever (12; 22) and a second deviation lever (13; 23), said levers having a second articulation point (34, 35; 44, 45); b) the two articulation points (34, 35; 44, 45) of the first deviation lever (12; 22) and second deviation lever (13; 23) are interconnected by means of a crossbar (14; 24) hinged thereto; c) the first deviation lever (12; 23) is a single-arm lever, whose second articulation point (34; 45) is located on one side of an imaginary connecting line (36; 46) of the bearings (16; 26) that are fixed to the frame and d) the second deviation lever (13; 22) is a dual-arm lever, whose second articulation point (35; 44) is located on the other side of an imaginary connecting line (36; 46) of the bearings (15; 25) that are fixed to the frame.
Abstract:
The invention relates to a chassis (3) that can be retrofitted to a front-wheel drive motor vehicle. The chassis (3) is provided with an axle arrangement (5, 17) and is linked to a motorized traction head (2) via a chassis connection (4) and reinforcements (8) of said chassis. The reinforcements (8) include an overlapping protruding shoulder (9) that rests upon a longitudinal beam (11) of the chassis (3) and is secured by means of several elements that are screwed into cupped forms. The shoulder (9) is guided in the preferably C-shaped longitudinal beam in a positive fit.
Abstract:
본 발명은 이동체를 구성하는 서로 다른 부품들을 연결해주는 회전식 디스크 서스펜션 시스템으로서, 이동체의 어느 한 부품에 회전 가능하게 연결되는 내부 디스크와, 이동체의 다른 부품에 결합되고, 내부 디스크와 서로 마주보게 배치되면서 내부 디스크에 회전 가능하게 결합되는 외부 디스크를 포함하여, 주행 중에 이동체에서 받는 힘을 선형운동에서 회전운동으로 변환해줌으로써 이동체의 동적 변형률 및 동적 응력에 보다 능동적으로 대응할 수 있고, 이로 인해 이동체가 운행 중에 울퉁불퉁한 요철 지형 또는 경사 지형을 만나더라도 기울어지지 않고 수평한 상태를 유지할 수 있다.
