| 20120019376 | UTILITY VEHICLE WITH PARKING BRAKE WARNING SOUND GENERATOR - A utility vehicle equipped with a parking brake is provided, which includes a parking brake warning sound generator immediately operated when the vehicle is driven while the parking brake is engaged. A parking brake warning sound generator is provided, which includes a parking brake detector detecting whether a parking brake is engaged; a drive detector detecting whether the vehicle is driven; a controller for receiving a signal from the parking brake detector and a signal from the drive detector to determine whether the vehicle is driven while the parking brake is being engaged; and a warning sound generator receiving the determination result from the controller to emit a warning sound for warning the driver that the vehicle is driven while the parking brake is being engaged. The parking brake warning sound generator emits a warning sound when a vehicle drive signal is detected while the parking brake is engaged. | 01-26-2012 |
| 20120018261 | FIXING STRUCTURE OF AUXILIARY BRAKING DEVICE FOR UTILITY VEHICLE - A fixing structure of an auxiliary braking device for a utility vehicle is provided, which includes a brake disc mounted on a driving shaft at which an output of a transmission is received; a brake pad mounted at a vehicle body in such a manner as to compress the brake disc by the cooperative operation with the manipulation of a brake lever mounted at a driver seat and to perform a braking operation; and a spline coupling part mounted at one end of the driving shaft in such a manner as to be fixedly coupled to a rear axle input shaft of a rear wheel differential gear so as to have the restriction in the axial movement thereof. | 01-26-2012 |
| 20120010042 | LOAD-SENSITIVE AUTOMATIC TRANSMISSION SYSTEM FOR AGRICULTURAL ELECTRIC VEHICLE - A load-sensitive automatic transmission system for an agricultural electric vehicle is provided, which includes a drive motor for generating a rotational power using electric power of a battery; a transmission for changing a rotational speed of the drive motor in multiple stages and outputting the changed rotational speed; a forward/reverse differential gear for transmitting the power of the transmission to wheels; a control unit for detecting a running state of the vehicle and a load state of the drive motor and determining a speed change time; and an actuator for operating the transmission in response to a signal from the control unit. Accordingly, it is possible to selectively provide high speed and torque to meet the needs of different situation, beyond the limitations of the motor drive performance of a conventional electric vehicle. | 01-12-2012 |
| 20080305930 | ENGINE STALL PREVENTION SYSTEM FOR INDUSTRIAL VEHICLES AND METHOD OF CONTROLLING THE SAME - Disclosed herein is an engine stall prevention system for industrial vehicles. The engine stall prevention system includes a transmission, which is configured such that a hydraulic shuttle valve for performing forward and reverse switching without requiring the operation of a clutch pedal, and a control unit for controlling the shuttle valve. The control unit receives a brake pedal operation signal from a brake detection unit for detecting the operation of a brake pedal, detects the traveling state of a vehicle using a traveling detection unit, determines whether the speed and engine RPM of the vehicle are equal to or less than respective preset values, and performs automatic control such that the shuttle valve enters a neutral state or a half-clutch state if it is determined that the vehicle speed is greater than the corresponding preset value and the engine RPM is equal to or less than the corresponding preset value. | 12-11-2008 |
