Abstract:
The present invention relates to an axle or bogie construction for a vehicle, comprising support means (3) provided between an axle (2) and a frame (1) of the vehicle, suspension means (7, 8) provided at the ends of the support means, the suspension means being secured at their one end to the support means and at their other end to the frame of the vehicle directly or indirectly, and a triangular support (5) attached at one point by means of a joint centrally to the axle and journalled at two points to the frame of the vehicle on its opposite sides. In order to reduce vertical movements of the frame of the vehicle when the axles are turned, the suspension means (8) on one side of at least one axle (2), when the axle is viewed in the longitudinal direction, extend essentially upwards from the support means (3) or the springs and the suspension means (7) on the other side of the axle essentially downwards.
Abstract:
Tandem rear axle air suspensions for trucks and truck-tractors wherein a non-reactive, roll compliant drive axle suspension (5) equipped with wheel slip control is combined with a roll stable, non-drive tag or pusher axle suspension (6) equipped with structure for transferring weight to the drive axle suspension (5). Preferably, the non-drive tag or pusher axle suspension (6) is a rigid beam suspension. The wheel slip control and the weight transfer structure may be either automatically or manually operated.
Abstract:
The invention concerns a suspension for vehicle wheels with wide tyres, e.g. low section tyres or double tyres. On utility vehicles with double tyres, rigid axles are almost always used. These axles have the advantage that variations in wheel loading are low. They suffer from the particular disadvantage, however, that the ground clearance is limited by the bridge design. Another disadvantage is that an uneven road surface has an adverse effect on relative wheel loading. The aim of the invention is to provide a suspension which has the advantages of the rigid axle without suffering from its disadvantages. The suspension (1) proposed is thus characterized by the provision of an additional degree of freedom which permits the wheel carrier (20) to execute an oscillating motion about a swivelling axis (10). The swivelling axis (10) lies approximately at the centre of the wheel (2) and extends approximately at the level of the plane of the road surface (8). The design proposed has the particular advantage that the wheel adapts automatically to the road surface. Variations in wheel loading caused by transverse forces are therefore low.
Abstract:
In a vehicle having a travelling mechanism that may be formed by wheels, crawlers, strips or skids secured to a vehicle frame or body, one or several swivelling devices (A, AA) are arranged between the travelling mechanism and/or the vehicle frame (2) or the wheel axles (5) on the one hand and the vehicle frame (1) and/or the vehicle body (7) on the other hand, and/or between the vehicle frame (1) and the vehicle body (7). The swivelling devices (A, AA) allow swivelling movements around one or several swivel axes (S1, S2, S3). The swivel axes (S1, S2, S3) extend or cross each other outside of the corresponding swivelling device (A, AA) in the direction of travel and/or transversely to the direction of travel and/or at an angle to the direction of travel.
Abstract:
The disclosure relates to a device in load-carrying vehicles with a so-called bogie lift, including a sprung (1) drive shaft which carries driving wheels and a running axle (2) on which running wheels are suspended. The running axle (2) is arranged, by means of a first lever (3) operating between the running axle (2) and one end of the spring assembly (1) of each respective driving wheel and rotatably disposed by means of an operating device (8) in relation to the frame (4) of the vehicle, to be raised and lowered, by means of a second lever (5) in relation to the frame (4) of the vehicle in order thereby to move the running wheels of the running axle (2) away from and into contact with that surface on which the vehicle rolls, in response to the axle pressure which is intended to be exerted on the surface. The movable, free end of the second lever (5) is arranged to actuate the first lever (3) a distance from the fulcrum of the second lever (5). At its movable end, the second lever (5) is designed with a plurality of surfaces (5a-5j; 6, 7) which are located at different distances from the fulcrum (10) of the second lever (5). The surfaces (5a-5j; 6, 7) are arranged to be turned, by the operating device (8), about the fulcrum (10) for load-transferring contact with different parts of the first lever (3).
Abstract:
A ball joint assembly (52) for connecting a tie rod (24) to a rack and pinion steering assembly (10) includes first and second housing members selectively mated to define a cavity (75) that receives the ball (54) of the tie rod and a bearing (76). The first housing member (72) includes a threaded portion matingly engaging a threaded portion disposed on the second housing member (74).
Abstract:
The invention relates to an axle and bogie construction for a commercial vehicle, in which the axle (1) is supported through a triangular support (4) and longitudinal support (7), respectively, to the frame (2) of the vehicle. On both sides of the frame (2), respectively, there is arranged a continuous and flexible load support construction (9) extending from the front end of the axle to its rear end and the axle or axles (1) are supported on said constructions. The construction comprises at least one flexible member (10), preferably resilient means (12) and support means (11), through which it is supported on the axle or axles and the frame so that the construction may pivot with respect to the journalling point of each support means, whereby each axle may turn and in addition to a normal resilient movement move in total conformity with the ground, and whereby the load of the axles in the bogie construction remains essentially constant.
Abstract:
A compact tag axle assembly (10) which may be retrofitted to an existing vehicle such as a tilting bed carrier (12) to allow the vehicle to comply with axle load regulations when operated over public roadways. The assembly (10) mounts behind the vehicle's rear axle such that the auxiliary wheels (16) are in close proximity to the rear vehicle wheels (18), with the support framework (24) of the auxiliary wheels (16) entirely behind the mounting location of these wheels. The assembly (10) consists of two interconnected auxiliary wheels (16) independently supsended by a transversely extending torsion axle (32) and connected to the vehicle through a centrally located pair of common mounting brackets (50). The assembly (10) has a minimal longitudinal displacement relative to the main vehicle rear wheels (18) and is easily mounted beneath an existing vehicle.
Abstract:
A balance suspension is intended for connection of the frame (7) of a transport means to the axles (5, 6). To simplify the assembly a C-shaped spring (1), consisting of a plate placed in its bending plane, is hingedly connected, in its middle part (2), to the axles (5, 6) of the transport means and by its end parts (3, 4) to the frame (7). The C-shaped spring (1) is connected to the frame (7) by means of shackles (10, 11) so that the ends of the spring (1) are capable of maximum vertical movements over a distance not exceeding half of the allowable deformation of the spring (1) in the horizontal direction.
Abstract:
An elastic suspension for the wheels of a vehicle having a frame with at least one axle comprises a pack (3) of springs which are located between the frame (1) and the axle (2) of the vehicle and mechanically connected to them. A bracket-shaped leaf spring (4) is mounted along the springs of the pack (3). The middle sections (5, 6) of the spring pack (3) and of the bracket-shaped leaf spring (4), respectively, are mechanically interconnected by means of a connecting assembly (7).
