A vehicle heat management system is provided. The system includes a radiator module having a battery radiator and an electric component radiator. A valve module has an inner space that is divided into a first chamber and a second chamber. Each chamber includes a first passage, a second passage, and a third passage. The first passage connects each chamber to a battery radiator, the second passage connects each chamber to a high-voltage battery core, and the third chamber connects each chamber to an electric component radiator and an electric component core. Each chamber includes therein a guide unit that selectively closes the first passage, the second passage, or the third passage depending on a rotation angle thereof. An actuator that is connected to the guide unit adjusts the rotation angle of the guide unit.

The disclosed is a damping force control apparatus for a vehicle which has a control device that stores a reference time that is set to a value within a predetermined range including the resonance period time of the front wheel. When determining that the predetermined vertical displacement portions are present in front of the front wheel on the basis of the detection result of a road surface sensor, the control device sets the damping coefficient of the shock absorber is set to the minimum value by the timing at which the front wheel reaches a predetermined vertical displacement portion, and returns the control of the damping coefficient to the control in accordance with a predetermined control law when a predetermined elapsed time based on the reference time has elapsed from the above timing.

A method and a system for displaying efficiency of regenerative braking for an environmentally-friendly vehicle to better educate drivers in regards to their braking habits and hopefully teach them how to improve the fuel efficiency of the vehicle through adjustment of their braking habits while improving the quality of a vehicle by displaying the regenerative braking efficiency in comparison to a total amount of braking during the braking of the environmentally-friendly vehicle on a cluster. In particular, a total amount of braking while the vehicle is braking, and a ratio of the amount of regenerative braking included in the total amount of braking is calculated by a controller. Then the controller determines whether the vehicle is stopped due to braking. Once the vehicle has stopped due to braking, the calculated ratio of the amount of regenerative braking is displayed on a cluster in the vehicle.

A shock absorber has a suspension spring bearing fixed securely to a cylinder. The shock absorber includes a cylinder, a suspension spring bearing on the cylinder, and a suspension spring. A suspension spring bearing includes a cylindrical shaped main body that covers an end of the cylinder, an annular spring bearing part formed on a periphery of the main body, a plurality of upper salients that project inwardly from the main body and that are spaced apart at even intervals around the circumference of the main body, in which the upper salients press against the periphery of the cylinder, and a plurality of lower salients that project inwardly from the main body and that are spaced apart at even intervals around the circumference of the main body at locations below those of the upper salients, in which the lower salients press against the periphery of the cylinder.

A motor drive device includes: a trailing arm that extends in a vehicle front-rear direction and includes a vehicle body-side attachment portion and wheel-side support portion, the vehicle body-side attachment portion formed on a forward portion side of the trailing arm and coupled to a vehicle body via a rubber bush, the wheel-side support portion formed on a rear side of the trailing arm and supporting a rear wheel; and a motor that is supported by the trailing arm and drives the rear wheel. The motor and the rubber bush are disposed in such a way that motor and the rubber bush are seen as being substantially aligned in a vehicle up-down direction when viewed in a vehicle width direction.

The present invention relates to a mirror device for a sun visor of a vehicle, in which when a cover of a mirror mounted to a sun visor is opened or closed, the mirror can be operated smoothly and completely, comprising: a mirror housing having a mirror and a cover sliding from the mirror housing to open or close the mirror, wherein the mirror housing and the cover are coupled to each other by an elongation member. Accordingly, the cover moves smoothly in a semi-automatic sliding manner by means of an elastic body, thereby restraining noise from being generated.

The invention discloses rubber bushing double-servo press fitting equipment and press fitting method. The equipment comprises a press-in servo mechanism, a reverse ejection servo mechanism and a mainrack, the press-in servo mechanism comprises a horizontal press-in upper plate and a horizontal press-in lower plate and is wholly fixed to the main rack through the press-in lower plate, the press-inupper plate and the press-in lower plate are connected through a vertical press-in guide column, the press-in guide column is provided with a press-in sliding table plate in a sliding manner, the sliding table plate is provided with a vertically-downward lower pressing head, and the press-in upper plate is provided with a press-in driving mechanism which is used for controlling the press-in sliding table plate to slide up and down along the press-in guide column; and the reverse ejection servo mechanism is located between the press-in upper plate and the press-in lower plate and comprises a reverse ejection driving mechanism, a reverse ejection rack and a reverse ejection head corresponding to the lower pressing head, and the reverse ejection head can be controlled by the reverse ejectiondriving mechanism to move up and down. The press-in state of a rubber bushing can be well guaranteed, and the press fitting quality of the rubber bushing is greatly improved.
