A parallel two-wheeled vehicle provided with braking means to directly brake two wheels includes: a body; a pair of drive units coaxially mounted to the body; a T-shaped handle to be gripped by a passenger; a longitudinal inclination detecting device of the body; and a brake lever. A brake detecting device to detect operational information of the brake lever is further provided. The body includes: a vehicle speed detecting device to determine a vehicle speed based on a relative angular velocity between the body and the wheels, which is detected by the drive units and based on an angular velocity detected by the longitudinal inclination detecting device; a target speed setting device to set a target vehicle speed based on an output of each of the brake detecting device and the vehicle speed detecting device; and a stabilization control device to control the vehicle to stably follow the target angle / target angular velocity / target vehicle speed. Further, powder brakes are incorporated in the drive units, respectively.

A zero-turn electric lawn mower, including: universal front wheel assembly A, emergency brake parking brake assembly B, integral welded frame assembly C, central mowing disc and height adjustment assembly D , cover and console assembly E, driving control assembly F, seat assembly G, wheel side deceleration drive wheel assembly H and energy system assembly I, the middle mowing disc and height adjustment assembly D It is composed of the mowing disc height adjustment assembly and the middle mowing disc assembly; the mowing disc height adjustment assembly includes the lifting joystick assembly, the lifting device rocker, the lifting connection weldment, the J-shaped side connecting shaft, the rear Transition connecting plate, J-shaped front shaft assembly, rotating shaft and bush seat; middle mowing disc assembly includes mowing disc casters, cutters, mowing disc front connecting plate, mowing disc, mowing disc rear connection panels and side row grass covers. By optimizing the design of the composition and structure of the lawnmower, it can meet the needs of horticultural lawn pruning management in complex environments.

The invention relates to a floating clamp disc drive-by-wire brake comprising a motor, a transmission mechanism, a one-way clutch, a bi-directional nut, a left-handed screw, a right-handled screw, a piston, a friction limiting device and the like. The motor drives the outer circle of the one-way clutch to rotate through the transmission mechanism, the one-way clutch drives the bi-directional nut to rotate, and through a bi-directional thread mechanism, the piston and a braking clamp body are driven to move in the opposite directions correspondingly. A friction piece is tightly pressed from the two sides of a braking disc through the same force, and thus the efficient braking effect is achieved. According to the floating clamp disc drive-by-wire brake, the structure is simple, work is reliable, the braking efficiency is high, the braking gap can be automatically adjusted, the influence caused by friction piece abrasion is compensated, the design of a control system is simplified, and the floating clamp disc drive-by-wire brake can be used for travelling braking and parking braking.

The invention discloses a foot parking braking and unlocking mechanism which consists of a braking assembly, a ratchet wheel piece, a connecting piece, a pawl and a pedal assembly, wherein the ratchet wheel piece is mounted on the braking assembly through a main shaft; the upper edge of the ratchet wheel piece is connected with the transmission rod of the braking assembly; an arc-shaped groove is formed below the ratchet wheel piece; a track is arranged below the ratchet wheel piece; a guide column which is mounted on the braking assembly is inserted into the arc-shaped groove; a return spring is arranged between the guide column and the ratchet wheel piece; the upper side and the lower side of the track respectively incline upwards and downwards from front to back; the front ends of the upper side and the lower side of the track are connected in a crossing manner; the rear ends of the upper side and the lower side of the track are connected through a folded side; positioning concave points are arranged at the rear ends; a ratchet wheel is arranged on the lower edge of the ratchet wheel; one end of each of the connecting piece and the pawl is pivoted on the braking assembly; another return spring is arranged between the connecting piece and the pawl; a guide pin matched with the track is arranged at the other end of the connecting piece; the other end of the pawl is matched with the ratchet wheel; another return spring is arranged between the other end of the pawl and the guide column; the upper end of the pedal assembly is fixed with the ratchet wheel piece. According to the foot parking braking and unlocking mechanism, the structure is simple, and foot parking unlocking can be conveniently achieved.

The present disclosure relates to a parking control system and a vehicle. The parking control system includes a manual parking control mechanism (1), an electric parking control mechanism (2), a switching mechanism (3) and a locking mechanism. The switching The mechanism (3) is configured to be switchable between a first position and a second position, in which the switching mechanism (3) can establish a relationship between the manual parking control mechanism (1) and the brake transmission connection, in the second position, the switching mechanism (3) can establish a transmission connection between the electric parking mechanism and the brake, and the locking mechanism selectively locks the switching mechanism In said first position or said second position. Through the above technical solution, the parking control system provided by the present disclosure can have both the electronic parking function and the manual parking function, and can achieve parking braking more safely and reliably.
