电动汽车
Abstract:
一种电动汽车，其包括再生制动器(34)和机械式制动器(9)，在车轮用轴承(4)中设置荷载传感器(41)，并且设置荷载对应再生制动限制机构(36)，上述荷载传感器(41)检测作用于路面与轮胎之间的车辆行进方向的荷载。该荷载对应再生制动限制机构(36)在荷载传感器(41)的输出达到设定值时，减少再生制动器(34)的制动转矩。另外，设置最大动作机构(35)，其根据车轮转数以及电池的充电状态，计算再生制动器(34)的最大可能的再生制动转矩，在指令范围内，以使再生制动器(34)的制动转矩为最大的方式而动作。
Abstract(English):

An electric vehicle provided with a regenerative brake (34) and a mechanical brake (9), wherein a wheel bearing (4) is provided with a load-adaptive regenerative brake restriction means (36), and a load sensor (41) for detecting the load in the vehicle progression direction acting between the road surface and tires. The load-adaptive regenerative brake restriction means (36) reduces the brake torque of the regenerative brake (34) when the output of the load sensor (41) reaches a set value. Moreover, a maximum actuation means (35) calculates the possible maximum regenerative brake torque of the regenerative brake (34) from the wheel rotational frequency and the battery charge state, and puts the brake torque of the regenerative brake (34) fully into action within a command range.
