Disclosed is an automobile, comprising an automobile body, wheels, a suspension device and a spoiler. The path of a fluid flowing through a lower spoiler surface is longer than the path of the fluid flowing through the upper spoiler surface, so that a lift force generated in the driving process of the automobile is reduced or even eliminated. The general understanding that the wheels bear the dead weight of the automobile, loads and all weights generated by the gravitational acceleration is changed. The dead weight of the automobile body is reduced by the lift force generated by the automobile body, the road holding of the automobile is improved after the wheels eliminate the lift force, and thus, the automobile can save more energy and can run more safely.

Provided is a protective member for coil springs, including a tube main body that covers a coil spring of a suspension, wherein the tube main body is made of thermoplastic polyurethane that includes a prepolymer and a chain extender, wherein the prepolymer includes diisocyanate and a polyol, wherein a molar ratio of the diisocyanate to a sum of the polyol and the chain extender (diisocyanate/(polyol+chain extender)) is 1.025 to 1.040 and a molar ratio of the chain extender to the polyol (chain extender/polyol) is 6 to 3.8.

A shock absorber provided with a suspension spring, the shock absorber includes a tube whose lower end portion is joined to a vehicle axle side portion provided with a tire, and a lower spring bearing that is provided on an outer circumference of the tube and supports a lower end of the suspension spring. An increased diameter part is provided on the outer circumference of the tube above the lower spring bearing, the increased diameter part having an outer diameter larger than an outer diameter of the tube.

A shock absorber provided with a suspension spring, the shock absorber includes a tube whose lower end portion is joined to a vehicle axle side portion provided with a tire, and a lower spring bearing that is provided on an outer circumference of the tube and supports a lower end of the suspension spring. An increased diameter part is provided on the outer circumference of the tube above the lower spring bearing, the increased diameter part having an outer diameter larger than an outer diameter of the tube.

A dust cover is configured to cover an outer side of a damper extending in a predetermined direction. The dust cover includes bellows portions and a flange portion. The bellows portions are inclined alternately toward a radially outer side and a radially inner side in an axial direction. The flange portion extends radially outward from a cylindrical portion of the dust cover. The flange portion protrudes radially outward from the cylindrical portion of the dust cover by a dimension larger than a height dimension in a radial direction between a radially inner end and a radially outer end of each of the bellows portions. A thickness of the flange portion is larger than a thickness of the radially outer end of each of the bellows portions.

An active roll stabilizer of a motor vehicle including an actuator (8) in the form of a swivel motor arranged so as to rotate about a longitudinal axis of the vehicle. The swivel motor has an essentially cylindrical housing (12) with a cover, first and second stabilizer halves (18, 19) are connected to respective ends of the actuator for the transmission of torque, and a wiring harness (1) has a first end and a second end. The harness includes cables (3, 4, 5) for the transmission of electric power and signals. The first end is connected to the actuator, by way of a plug (2), and the second end is arranged positionally fixed in the vehicle at a cable transfer point (20). The cover forms a dry space and has a plug receiving opening, in its periphery, into which the plug can be inserted, in the radial direction, and secured.

A cover is disclosed for a chassis control arm which includes at least one bearing mount for a control arm bearing. The cover is formed separately from the chassis control arm and covers in the installed state at least part of the underside of the chassis control arm. Arranged on the cover is an extension which is intended as buffer and extends from the cover in the direction of the control arm bearing.

A protective sheet enveloping an air suspension module of a vehicle is disclosed. The protective sheet comprises a first edge, a second edge, a third edge, a fourth edge, and a middle portion. The first edge, the second edge, the third edge, and the fourth edge having a pleat with a plurality of incises. The third edge and the fourth edge are in a perpendicular orientation with respect to the first edge and the second edge. The middle portion having a mesh encapsulated within the pleat of the first edge, the second edge, the third edge, and the fourth edge. The protective sheet envelopes around an outer circumferential surface of the air suspension module using fastening means. The plurality of incises provide flexibility for easy installation of the protective sheet over the air suspension module. The protective sheet protects the air suspension module during operation of the vehicle.

A shock absorber provided with a suspension spring, the shock absorber includes a tube whose lower end portion is joined to a vehicle axle side portion provided with a tire, and a lower spring bearing that is provided on an outer circumference of the tube and supports a lower end of the suspension spring. An increased diameter part is provided on the outer circumference of the tube above the lower spring bearing, the increased diameter part having an outer diameter larger than an outer diameter of the tube.

A strut-type damper is disclosed. The damper has a shock absorber having a housing with a telescoping piston rod, a coil spring, an upper spring seat operably coupled to a distal end of the piston rod, and a lower spring seat operatively coupled to the housing. The upper and lower spring seats capture the coil spring therebetween. The lower spring seat has a base portion having an opening for receiving the housing and is fixedly securable to the housing. A generally circumferential wall portion extends from the base portion and forms a catcher for catching a broken portion of the coil spring if the coil spring fractures. An impact absorbing structure is formed on the lower spring seat adjacent both of the catcher and the base portion, and is configured to be crushed in the event of a fracture of the coil spring.
